[QUOTE="Manator, post: 345479, member: 9561"] Thanks Adrian, I have lost count of the times I have met other sparks who believe all they learned at college does not mean anything in the real world. Calculations are important especially if you are designing the circuit. It is also vital in understanding why it has been installed by others. A designer may use a lower rated cable for a certain use because he has carefully assessed the diversity and calculated that the cable would suffice given the circumstances of use. To be fair in most domestic installations the best option is to give a fair amount of headroom. In other words go larger than required. In industrial situations its all down to costs, and getting a cable to do what is required for the minimum amount of outlay. [/QUOTE]
